Launched on 16 May 2026, the Audemars Piguet × Swatch "Royal Pop" collaboration caused a sensation: a pocket watch with an octagonal Bioceramic case, supplied with a calfskin lanyard to wear around the neck, on a bag or wrapped around the wrist. Singapore's tropical climate is hard on leather, and many Royal Pop owners have asked us how to wear their watch on the wrist every day. That is exactly what the KronoKeeper rubber strap + case set is for — available now at MisterChrono Singapore in seven colours at S$180.

Turn Your AP x Swatch Pocket Watch into a Wristwatch
The idea is simple: the watch slips into a rubber case shaped to its octagonal body, and a 27 × 20 mm rubber strap (27 mm at the case, 20 mm at the buckle) attaches to the case. The case protects the watch from everyday knocks while keeping a slim profile on the wrist, and the strap closes with a steel pin buckle. Your original lanyard stays untouched, so you can switch between the two in seconds.

Soft Rubber, Made for Every Day
The strap is made of soft, flexible, high-grade vulcanised rubber: waterproof, hypoallergenic, and resistant to UV, sweat and saltwater. In Singapore's year-round heat, a rubber strap simply makes more sense than a leather lanyard: it shrugs off sweat, pool water and a weekend on Sentosa, and a quick rinse is all the care it needs.

Frequently Asked Questions
Does the set fit every Royal Pop model?
The set is designed for the Lépine models of the AP × Swatch collection (crown at 12 o'clock, two hands). It is not intended for the Savonnette versions (crown at 3 o'clock, small seconds). If in doubt, send us a photo of your watch or visit our boutique at Mandarin Gallery on Orchard Road and we will check before you order.
Is it difficult to fit?
Not at all: the watch clips into the case in seconds and the strap is ready to wear. Our team can also fit it for you in store.
Is this an official product?
No. It is an independent accessory by KronoKeeper, the French premium watch accessories brand, and is not manufactured or endorsed by Swatch Group or Audemars Piguet. Watch not included.
